摘要
为了解城市地下空间水灾研究进展,预测其发展趋势,系统调研城市地下空间水灾的相关文献,并从试验和数值模拟角度,归纳总结城市地下空间洪水漫延规律、地下空间阶梯流动力学特征及其对受灾人员撤离影响的研究进展,分析当前研究内容和研究方法中存在的局限和不足,预测城市地下空间水灾的研究趋势。研究表明,当前研究趋势是建立计算精度和计算效率较高的大尺度复杂多层地下空间洪水漫延问题数值计算模型,并研究地下空间复杂形态楼梯上洪水水流动力学特征及其对人员安全撤离的影响等。
To have a general overview of the research progress of urban underground flooding and predict the research trends, a systematic and thorough literature review was carried out. From the perspective of experiment and simulation, the research advances of the propagation law of underground flooding and the dynamic characteristics of the staircase flow together with the flooding effects on safe evacuation were summarized. The limitations and deficiencies of the research contents and methods of underground flooding were furthermore discussed and analyzed. Finally, the research trends of urban underground flooding were presented. Research results show that developing high-fidelity and high-efficiency numerical model for simulating flooding in complex multi-storey underground spaces, and investigating the dynamic characteristics of the staircase flow and its effects on the underground evacuation are currently the main research trends.
